Columbia Skate Park Construction Detail & Photos

The Columbia Skate Park was designed and constructed with in-house Parks and Recreation staff. The staff has received many inquiries from other municipalities since the completion of the park. The following information is provided as a service to assist other communities looking for design information.


Reinforcing was used throughout the facility, both in the flatwork and in the skating elements. The pattern was generally 12″-14″ o.c. and each pour was pinned to the adjacent pour.


The concrete finish is a slick-troweled surface. The elements were hand-troweled, while the floor was power-troweled. The floor surface was treated with a sealer to reduce potential damage from water.


The entire park has positive drainage to drop inlets that are inconspicuously built into steps on the west side of the facility. The east half drains off-site without the need for inlet structures.


All concrete was 6 bag mix and free of calcium chloride unless temperatures required the admix for setup time and finishing.


The skate park lies at the north end of the north-south runway of what was for many years Columbia’s municipal airport. The entire skate park was constructed on top of the former runway’s existing aircraft turn-around concrete slab (5.5″ thick) that was poured almost 50 years ago. A gravel isolation layer (1″ thick) was added to separate the new concrete from the existing slab. This was done to help reduce the potential reflective cracking that might occur over time.


The decision was also made to construct the entire area without the use of expansion joints. The reasoning was based on the need to maintain a smooth surface and the belief that the over-expansion capabilities of the surface was such that the expansion joint method was not going to greatly enhance the structural integrity of the project. The skate park has now survived over 2 ½ years without any structural problems, suggesting that the decision to not include expansion joints was correct.


The joint patterns were determined by evaluating each pour relative to the individual components, which were constructed in advance of any floor work. The grind rails and steel coping designs were determined by the skate board design committee. This committee was comprised of local skaters. Parks and Recreation worked together with the committee early in the design phase to outline the basic park layout and feature designs. The critical detail specifications for the coping, grind rails, radius size for all transitions, degree of slope for the numerous flat ramp areas, height of the various elements, spacial relationships within the layout, and any other details were all established early in the design phase.


Since many projects, including the skate park, are constructed in-house, Columbia Parks and Recreation generally does not calculate per-yard costs. Also, labor costs are not charged against a development project when in-house labor is used, so the following figures were applied to the skateboard facility materials only. Another source of funding was used to build the 101-car parking area for the Skate Park.

Project Budget – $64,000:

  • $39,000 from City General Fund
  • $25,000 from the local Columbia Cosmopolitan Club
